If you need to revert a refund that was made to a player's account (a balance credit was issued to their account) instead of their original form of payment, you just go to Player's Account > Billing > Paid Fees
Look for the refund and click on the blue 'R'
Now click on the date of the refund
Click 'Revert Refund' button
Click Yes
Now we need to refund this amount back to the credit card. Click Adjust Balance / Refund
The Adjustment Type should be Refund a Fee. Now Click Refund to the correct line item.
Now process back to the credit card.
Now the refund is back on the credit card and can be seen on the Billing Tab - All Transactions.
